Hi
I think you would have to use the overide method, then:
get csv field value
$csvField = $cck->getValue('my_csv_field') // $csvField = "1,2,3,4,5,6";
$arr = explode(",", $csvField);
Then do a foreach loop on $csvArray and add it to an outputArray
$outputArray = '';
foreach ($arr as $value) {
$outputArray .= '<h2>' . $value . '</h2>;
}
echo $outputArray;
